But the question is, would you get an accurate assessment if these old timers aren't playing at 100% intensity knowing that the playoffs are a pipe dream?

True. But i think where theyre at at this stage of their careers, you pretty much know what and what not youre going to get out of them, although it would help if they play with goal and purpose, i think one would be able to gauge if this 5 would work, or if certain pieces need to be alternated, or do they need to acquire more strength on this position, etc etc even if your stars are not playing balls out.

By assessing the situation, i meant was which positions need more help/depth, which groupings would statistically work better, etc etc.

I think it also lessens the pressure on not just the two acquisitions but the whole team as well. No scrambling to make things fit at the moment to make the playoffs but rather worry about working on chemistry and defining roles for the coming season.
